缺碘可影响儿童的智力和神经系统的发育已为人们所熟知,但高碘是否影响胎儿的脑和神经系统的发育,是否也出现地方性克汀病患者,仍是一个争论中的问题。到目前为止,国内外尚未见到高碘地甲病区有克汀病患者的报道。近几年有不少学者提出;在高碘地甲病流行区也和缺碘病区一样,在所谓正常人群中存在相当数量不同程度的错力低下者,这是一个很值得重视和探讨的问题。 It is well-known that iodine deficiency affects the development of children’s intelligence and nervous system. However, whether high iodine affects fetal brain and nervous system development, and whether local cretinism also occurs, is still a matter of debate. So far, no reports of cretinism have been reported in high-iodine-resistant areas in China and abroad. In recent years, many scholars have proposed that in the high iodine-endemic area and iodine-deficiency area, there are a considerable number of people in the so-called normal population with varying degrees of malnutrition, which is worthy of attention and discussion problem.
